I'm still waiting for someone to make a map with only certain aircraft enabled at the forward fields.
First wish list HTC for that to be an MA terrain standard modified condition. Like allowing the terrain builder a number of airfields that can be limited similar to the requirement of three un-capturable bases. You are required to limit 163 to a single un-capturable field. And required to make three fields un-capturable. But, airfields, GV bases, ports and CV's have set rides enabled by default. The first time a limited ride airfield acted like ENY at some critical juncture in defending a country, the MOB would be in here demanding your head.
We thought during the closed alpha when the new GV bases and ports with runways were introduced, that HTC had moved in that direction. So we tested extensively what planes, with what load outs you could get out of and into those bases. The 1x1 GV base with the asphalt short runway can launch and land up to twin engine fighters with light fuel and light ord loads. As you see on ndisles in the center, a small field takes up the same grid area as the 1x1 GV base with a full offering of aircraft and the same GVs.
I suspect the new small airfield may have been the response to all of the previous wishes for limited ride forward fields that can be placed in the "in between" 8, 12.5 and 19 mile "no man's land" that has been wished for over the last 15 years. As for forward fields, the condition called a front line is so fluid in the MA open world as to be none existent in terms of being useful.
Almost every field in the game has the potential to being a forward field at some point and reasonably why all planes and GVs are available except for the 163. Supposedly in the MA open world, each base that can be captured is a single limited war, so needs all of it's rides available to the defenders to fight that single small war. Your wish is something more useful in a game with two countries fighting to dominate the arena as the condition of winning that single large scale war.
You do have the AvA, SFO, and Special Events which operate in the traditional two side war condition.
